Should a requisition or Purchase Order be flagged when using a vendor flagged for review on financia

In using Financial Sanctions on the procure to pay side, I saw a requisition was not flagged for a vendor that was in a review status for financial sanctions. Is this the way the system is supposed to be or should it have been flagged? I was able to create the requisition, copy it into a PO then dispatch the PO for the vendor that was in a review status on financial sanctions.
